Turns out it was more than just a hiccup - I was bitten by a firmware 
bug in my Crucial M4 SSD disk 
http://forum.crucial.com/t5/Solid-State-Drives-SSD/Firmware-Update-Notifications/m-p/80282#M24370

"an incorrect response to a SMART counter will cause the m4 drive to 
become unresponsive after 5184 hours of Power-on time. The drive will 
recover after a power cycle, however, this failure will repeat once per 
hour after reaching this point."

If any of you have Crucial M4 SSD disks in use, I'd recommend checking 
the firmware version ASAP - it must be version 0309 or 000F. "smartctl 
-a" on Linux can tell you.
